To cZZ whom it may concern:

Be it known that 1, LE ROY H. RAND, a

- citizen of the United States, and resident f New York city, borough of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Methods of Manufacturing Dress- Shields, of which the following is a full,

clear, and exact description.

Among the principal objects which the present invention has in view are: to reduce the cost of manufacture of shields of the character mentioned; to shorten the time factor in the manufacture of said shields; and to improve the structure of said shields.

Drawings.

Figure 1 is a view showing the two pieces of a dress shield overlaid, one independent of the other, in the position in which they are placed prior to turning the connecting seam.

Fig. 2 is a diagram showing the operating table on which the shield members are held during the operation of turning the seam, the two members of the shield being shown as originally disposed onthe table, and as corresponding to the arrangement shown in Fig. 1.

Fig. 3 shows the method employed for lifting the flap of the seam or the operation succeeding the operation shown in the previous figure.

in the operation succeeding that shown in the previous figure.

Fig. 5 shows the arrangement of the various members during the compression of the overlaid flap of the body of the shield.

I Fig. 6 is a view of the completed shield.

Description.

Heretofore, in the manufacture of dress shields, the flap which forms the seam has been, of necessity, turned by hand. After the flap is turned, the seam has been completed by rolling the flap down upon the body of the shleld which has previously been provided with a suitable cement. The two pieces from which the shield has been constructed have been, and are at present cut by means of a suitable die.

When constructing shields in conformity with'the above described method, it is necessary to exercise great care to prevent wrinkling and crumphng of the seam. This consumes time and requires a great amount of hand labor where the production is large.

lVhen constructing shields in conformity with the herein described method, it is found expedient and beneficial to the product to turn the flap 10, of the piece 11, which in conjunction with the piece 12, forms the shield. The flap 10 is lifted bodily, and in one operation, from the position shown in Figs. 1 and 2 of the drawings, to the position shown in Fig. 3 of the drawings, a curved blade or plunger 13 being employed for this purpose. The plunger 13 conforms to the edge of a table or plate 14, upon which normally is held a clamp plate 15. The plate 15 closes upon the two pieces 11 and 12, and is contiguous with the curved edge of the piece 12. When the flap 10 is raised to the position shown in Fig. 3, it is disposed in the path of a plunger 16. The plunger 16 is then moved forward, the movement of such plunger being coincident with the with drawal of the plunger 13. The plunger 16, and the plunger 13 are disposed in the position indicated in Fig. at of the drawings. \Vhen the parts are so disposed, it will be noted, the flap 10 is loosely overlaid on the piece 12 and over the cemented area 17 thereof. The plunger 16 is then depressed on the flap l0, pressing the same on the pieces 11 and 12. When the pressure has been applied sufficiently long, the plunger 16 is raised and retracted to the position shown in Fig. 2 of the drawings. The blank 15 is then lifted and the completed shield is removed from the plate 14.

From the foregoing, it will be seen that the seam formed by the flap 10 is smooth and free of wrinkles or other imperfections, the material having been constantly controlled from the time that the blank 15 started to lift the flap 10. When the flap 10 is overlaid, the edge thereof is stretched slightly, due to the fact that the raw edge of the flap 10, as originally formed, is converted from an inner curved edge to an outer curved edge, or in other words, the edge of the flap is slightly stretched or held under tension.

It is obvious that the width of the seam as formed with the flap 1O isof a more uniform dimension than if laid in place by the rolling process above indicated. Also, it is evident that the time required for the manufacture shields consisting in producing component a of shields, and therefore the quantity of Claims. 7 1. The method of manufacturing dress sheets of material for forming a shield, said parts having a curved edge for forming the arm-hole portion of the shield, one of said sheets 'being slightly longer-than the other of said sheets; thenpreparing the edges of said sheets With a suitable adhesive; then superposin-g said sheets so that the curved edge of the longer of said sheets extends beyond the curved edge of the shorter of said sheets; then up-turning the entire curved edge of the longer sheet in the single and same operation; then over-turning the entire up-turned edge 'onth'e edge of the short sheet in the same and single operation; then pressing the entire lapped edges by a single operation.

in paired relation to form parallel curved edges for constructing the arm-hole seam of the shield, one of said sheets being longer than the other for being over-turned thereupon; then preparing the edge of the longer 01 said sheets for adhesively uniting it to the shorter of said sheets; then clamping said sheets innnovabl'y and at the edge of the shorter of said sheetsby a clamp conforming With said edge of the shorter sheet; then liftinig sinn'iltaneously the entire length of the edge of said longer sheets having-adhesive applied thereto, said edge'being lifited to a position perpendicular to the body of said sheets; then retracting the member pressing the superposed sheets; then'pressing the entire length of said u'p-turned edge over upon the edge of said shonter sheet.
